Description

L'invention est relative à un lave-linge à fonctionnement automatique sous la commande d'un programmateur.The invention relates to a washing machine with automatic operation under the control of a programmer.

Un lave-linge comporte habituellement un tambour perforé dans lequel est disposé le linge à laver et qui tourne dans une cuve destinée à contenir l'eau de lavage ou de rinçage. A l'heure actuelle pratiquement tous les lave-linge d'usage domestique sont à fonctionnement automatique, l'utilisateur ayant seulement à composer un programme -à l'aide de touches, boutons rotatifs ou analogues sur le tableau de commande de la machine-et à commander le démarrage de l'exécution du programme ainsi composé.A washing machine usually comprises a perforated drum in which is placed the laundry to be washed and which rotates in a tub intended to contain the washing or rinsing water. At present practically all washing machines for domestic use are automatic, the user having only to compose a program -with the help of keys, rotary knobs or the like on the control panel of the machine- and to command the start of the execution of the program thus composed.

Une opération de lavage exécutée par le lave-linge sous la commande d'un programmateur comprend plusieurs phases : la première est une phase de prélavage, la seconde est une phase de lavage à laquelle succède habituellement un refroidissement ; puis on procède à plusieurs (par exemple quatre) opérations de rinçage, et la dernière phase est l'essorage du linge. Bien entendu certaines de ces opérations peuvent, au gré de l'utilisateur, être supprimées par exemple le prélavage ou l'essorage.A washing operation carried out by the washing machine under the control of a programmer comprises several phases: the first is a prewash phase, the second is a washing phase which is usually followed by cooling; then several (for example four) rinsing operations are carried out, and the last phase is the spinning of the laundry. Of course some of these operations can, at the option of the user, be omitted, for example prewash or spin.

Dans certains lave-linge les conditions d'exécution du lavage dépendent de la charge de linge introduite dans le tambour. Ainsi, pour le lavage et le rinçage, il est déjà connu de faire dépendre la quantité d'eau introduite dans la cuve du poids de linge. Il est aussi connu de faire dépendre de ce même poids de linge la durée totale de fonctionnement des diverses phases.In some washing machines the conditions for washing depend on the load of laundry introduced into the drum. Thus, for washing and rinsing, it is already known to make the amount of water introduced into the tank depend on the weight of the laundry. It is also known to make the total duration of operation of the various phases depend on this same weight of laundry.

Ainsi pour une même efficacité de lavage on peut, pour une quantité de linge plus faible, réduire la quantité d'eau utilisée ou le temps d'exécution du programme de lavage.Thus, for the same washing efficiency, it is possible, for a smaller quantity of laundry, to reduce the amount of water used or the execution time of the washing program.

Selon un premier de ses aspects, l'invention se rapporte à un lave-linge à programmateur comprenant un moteur entraînant un arbre portant des cames agissant sur des interrupteurs ou commutateurs qui commandent le fonctionnement des divers organes du lave-linge telles que l'électrovanne d'introduction d'eau, la résistance de chauffage de l'eau, la pompe de vidange, ainsi qu'un second moteur relié à l'arbre pour le faire tourner plus rapidement que le premier moteur lors de séquences déterminées du programme de lavage, qui est caractérisé en ce que le second moteur est utilisé pour raccourcir ou supprimer certaines phases du programme en fonction de la charge de linge. Ce second moteur est par exemple relié à l'alimentation en énergie électrique par l'intermédiaire d'interrupteurs dont l'état ouvert ou fermé a été déterminé lors de la composition du programme en fonction de la charge de linge, le cablage étant tel que le second moteur est alimenté par l'intermédiaire d'un tel interrupteur fermé, et d'un ou plusieurs interrupteurs commandés par les cames lors des phases à supprimer ou raccourcir.According to a first of its aspects, the invention relates to a programmer washing machine comprising a motor driving a shaft carrying cams acting on switches or switches which control the operation of the various organs of the washing machine such as the solenoid valve for introducing water, the water heating resistor, the drain pump, as well as a second motor connected to the shaft to make it turn faster than the first motor during specific sequences of the washing program , which is characterized in that the second motor is used to shorten or delete certain phases of the program depending on the load of laundry. This second motor is for example connected to the electrical energy supply via switches whose open or closed state was determined during the composition of the program as a function of the load of laundry, the wiring being such that the second motor is supplied by means of such a closed switch, and one or more switches controlled by the cams during the phases to be eliminated or shortened.

Un tel programmateur comportant deux moteurs est déjà connu. Mais jusqu'à présent le second moteur n'a été utilisé, pour raccourcir ou supprimer certaines phases de fonctionnement du lave-linge, qu'en fonction du type de linge à laver. Avec la présente invention le second moteur est utilisé pour faire dépendre la durée de certaines phases de la charge de linge. Dans une réalisation l'adaptation du programme de lavage à la nature du linge est obtenue en prévoyant plusieurs secteurs distincts sur la came entraînée par le premier moteur, chaque secteur correspondant donc à un type de linge; dans ce cas la sélection du programme en fonction de la nature du linge est obtenue en positionnant, à partir du tableau de commande de la machine, la came sur le secteur considéré. Le second moteur du programmateur a alors exclusivement un rôle d'adaptation du programme à la charge.Such a programmer comprising two motors is already known. But until now the second motor has been used, to shorten or eliminate certain operating phases of the washing machine, only according to the type of laundry to be washed. With the present invention, the second motor is used to make the duration of certain phases depend on the load of laundry. In one embodiment, the adaptation of the washing program to the nature of the laundry is obtained by providing several distinct sectors on the cam driven by the first motor, each sector therefore corresponding to a type of laundry; in this case the selection of the program according to the nature of the laundry is obtained by positioning, from the machine control panel, the cam on the sector in question. The second motor of the programmer then exclusively has the role of adapting the program to the load.

Selon un second de ses aspects, l'invention se rapporte à un lave-linge caractérisé en ce qu'il comprend des phases de fonctionnement dont les conditions d'éxécution dépendent de la charge de linge alors que la phase de refroidissement et, de préférence, la première phase de rinçage sont effectuées dans des conditions, notamment la quantité d'eau, indépendantes de la charge de linge.According to a second of its aspects, the invention relates to a washing machine characterized in that it comprises operating phases whose execution conditions depend on the load of laundry while the cooling phase and, preferably , the first rinsing phase are carried out under conditions, in particular the amount of water, independent of the load of laundry.

Cet autre aspect de l'invention, qui peut être utilisé indépendamment du premier, résulte de la constatation suivante : dans un lave-linge ne comportant pas de doseur automatique de produit lessiviel, l'utilisateur choisit en général la dose de ce produit qui correspond à la charge maximum. Ainsi pour une faible charge, si la quantité d'eau utilisée lors de la phase de refroidissement était en proportion de la charge il en résulterait une dilution insuffisante du produit lessiviel ce qui, d'une part, altèrerait la qualité du rinçage ultérieur et, d'autre part, risquerait de perturber le fonctionnement de la pompe de vidange en raison de la présence de la mousse résultant de l'insuffisance de la dilution. C'est pourquoi pour la phase de refroidissement, et de préférence pour le premier rinçage, la quantité d'eau utilisée correspond à la charge maximum; de préférence également la durée de ces phases est indépendante de la charge de linge.This other aspect of the invention, which can be used independently of the first, results from the following observation: in a washing machine not comprising an automatic dispenser of detergent, the user generally chooses the dose of this product which corresponds at maximum load. Thus for a low load, if the amount of water used during the cooling phase was in proportion to the load, this would result in an insufficient dilution of the detergent which, on the one hand, would affect the quality of the subsequent rinsing and, on the other hand, would risk disturbing the operation of the drain pump due to the presence of foam resulting from insufficient dilution. This is why for the cooling phase, and preferably for the first rinsing, the amount of water used corresponds to the maximum load; preferably also the duration of these phases is independent of the load of laundry.

D'autres caractéristiques et avantages de l'invention appara'itront avec la description de certains de ses modes de réalisation celle-ci étant effectuée en se référant au dessin ci-annexé sur lequel la figure unique montre une partie du câblage d'un programmateur de lave-linge selon l'invention.Other characteristics and advantages of the invention will appear with the description of some of its embodiments, this being carried out with reference to the attached drawing in which the single figure shows part of the wiring of a programmer. washing machine according to the invention.

Dans l'exemple le lave-linge est du type à tambour perforé contenant le linge et tournant autour d'un axe horizontal. Ce tambour perforé est disposé à l'intérieur d'une cuve contenant l'eau de lavage ou de rinçage. Le brassage du linge est obtenu grâce à des saillies que comporte la surface interne du tambour.In the example, the washing machine is of the perforated drum type containing the laundry and rotating around a horizontal axis. This perforated drum is placed inside a tank containing the washing or rinsing water. The mixing of the linen is obtained by means of projections which comprise the internal surface of the drum.

Sur le dessin on n'a representé que les éléments nécessaires à la compréhension de l'invention.In the drawing, only the elements necessary for understanding the invention have been shown.

Le programmateur comporte un premier moteur synchrone 12 relié d'un côté à une borne 11 du secteur d'alimentation en énergie électrique et, de l'autre, à un conducteur 15 connecté lui-même à l'autre borne 10 du secteur par l'intermédiaire d'un interrupteur 14. L'arbre (non représenté) de ce moteur 12 porte des cames (également non représentées) qui agissent sur l'état d'interrupteurs ou commutateurs. Ainsi l'état de ces interrupteurs dépend de la posi tion angulaire de l'arbre du moteur 12. Ce dernier constitue donc l'horloge de mesure de temps du déroulement du programme.The programmer comprises a first synchronous motor 12 connected on one side to a terminal 11 of the electrical power supply sector and, on the other, to a conductor 15 connected itself to the other terminal 10 of the sector by the 'Intermediate of a switch 14. The shaft (not shown) of this motor 12 carries cams (also not shown) which act on the state of switches or switches. Thus the state of these switches depends on the angular position of the motor shaft 12. The latter therefore constitutes the time measurement clock of the progress of the program.

Les interrupteurs ou commutateurs du programmateur sont branchés de façon à mettre en ou hors tension les organes actifs du lave-linge comme on le verra plus loin. Ces interrupteurs ou commutateurs permettent aussi de mettre en ou hors tension un second moteur 30 faisant partie du programmateur qui fait tourner l'arbre portant les cames à une vitesse de rotation sensiblement supérieure à la vitesse imposée par le moteur 12. Autrement dit quand le moteur 30 est sous tension des phases de fonctionnement du lave-linge qui, dans le cas contraire (c'est-à-dire le moteur 30 à l'arrêt), auraient été éxécutées en un temps déterminé sont écourtées ou supprimées. Le câblage est donc tel qu'il est prévu pour un programme maximum : charge maximum, température maximum de l'eau de lavage et le moteur 30 est utilisé pour écourter ou supprimer certaines plages quand la charge n'est pas maximale.The switches or switches of the programmer are connected so as to turn on or off the active components of the washing machine as will be seen below. These switches or switches also make it possible to switch on or off a second motor 30 forming part of the programmer which rotates the shaft carrying the cams at a speed of rotation substantially greater than the speed imposed by the motor 12. In other words when the motor 30 is energized during the operating phases of the washing machine which, otherwise (that is to say the motor 30 at a standstill), would have been executed in a determined time are shortened or eliminated. The wiring is therefore as provided for a maximum program: maximum load, maximum temperature of the washing water and the motor 30 is used to shorten or delete certain ranges when the load is not maximum.

La borne 10 du secteur est connectée, par l'intermédiaire d'un autre interrupteur 13, à un thermostat réglable 16 lequel est lui-même relié à une première borne d'une résistance 17 de chauffage de l'eau dans la cuve du lave-linge dont l'autre borne est reliée à un plot 19, d'un pressostat 19 dont la borne commune 192 est reliée à un conducteur 18 lui-même connecté à la borne 11 du secteur.The terminal 10 of the sector is connected, via another switch 13, to an adjustable thermostat 16 which is itself connected to a first terminal of a resistor 17 for heating the water in the lava tank -line whose other terminal is connected to a pad 19, a pressure switch 19 whose common terminal 19 2 is connected to a conductor 18 itself connected to terminal 11 of the sector.

Le thermostat 16 est un interrupteur qui est fermé lorsque la température de l'eau de la cuve est inférieure à une valeur donnée, réglable, et est ouvert lorsque la température dépasse cette valeur. Le pressostat 19 est un commutateur à deux positions. Il est dans la première position, les bornes 19, et 192 étant reliées entre elles, quand le niveau de l'eau dans la cuve dépasse une valeur prédéter:sh minée N,. Ce pressostat est dans la seconde position, les bornes 192 et 193 étant connectées entre elles, quand le niveau de l'eau est au-dessous de la valeur N,.Thermostat 16 is a switch which is closed when the temperature of the tank water is lower than a given, adjustable value, and is opened when the temperature exceeds this value. The pressure switch 19 is a two-position switch. It is in the first position, the terminals 19 and 192 being interconnected when the water level in the tank exceeds a predetermined value: sh mined N ,. This pressure switch is in the second position, the terminals 192 and 193 being connected together, when the water level is below the value N ,.

La seconde borne 193 du pressostat 19 est reliée au conducteur 15 par l'intermédiaire, d'une part, d'une électrovanne 20 et, d'autre part, d'un commutateur 21 à deux positions dont la borne commune 21, est reliée directement au conducteur 15 et la première borne de connexion 212 est reliée à l'électrovanne 20. La seconde borne de connexion 213 du commutateur 21 est reliée à une seconde électrovanne 22 elle-même connectée à la borne 193 du pressostat 19. Ce commutateur 21 est commandé par une came du programmateur.The second terminal 193 of the pressure switch 19 is connected to the conductor 15 via, on the one hand, a solenoid valve 20 and, on the other hand, a two-position switch 21 whose common terminal 21, is connected directly to the conductor 15 and the first connection terminal 212 is connected to the solenoid valve 20. The second connection terminal 21 3 of the switch 21 is connected to a second solenoid valve 22 itself connected to the terminal 193 of the pressure switch 19. This switch 21 is controlled by a programmer cam.

La borne 193 du pressostat 19 est aussi connectée à une première borne d'une troisième électrovanne 23 reliée au conducteur 15 par l'intermédiaire d'un autre commutateur 24, lui aussi faisant partie du programmateur. La seconde borne de connexion 24, de ce commutateur 24 est reliée au moteur de la pompe 25 de vidange qui, de l'autre côté, est connectée au conducteur 18.Terminal 19 3 of the pressure switch 19 is also connected to a first terminal of a third solenoid valve 23 connected to the conductor 15 by means of another switch 24, also part of the programmer. The second connection terminal 24 of this switch 24 is connected to the motor of the drain pump 25 which, on the other side, is connected to the conductor 18.

La première borne 30, du moteur 30 est reliée au conducteur 15 tandis que sa seconde borne 302 est connectée à une première borne 31, d'un commutateur double 31 à quatre bornes et deux connecteurs, faisant partie du programmateur. Une autre borne 312 du connecteur 31 est reliée au point commun au thermostat 16 et à la résistance 17; la troisième borne 313 est reliée au conducteur 18 par l'intermédiaire d'un interrupteur 32 qui est fermé quand l'utilisateur a actionné une touche indiquant "charge 1 Kg". La quatrième borne 31, du commutateur 31 est aussi reliée au conducteur 18 par l'intermédiaire d'un interrupteur 33 fermé quand la charge de linge est de l'ordre de 2 kg.The first terminal 30, of the motor 30 is connected to the conductor 15 while its second terminal 302 is connected to a first terminal 31, of a double switch 31 with four terminals and two connectors, forming part of the programmer. Another terminal 31 2 of the connector 31 is connected to the point common to the thermostat 16 and to the resistor 17; the third terminal 31 3 is connected to the conductor 18 via a switch 32 which is closed when the user has pressed a key indicating "load 1 Kg". The fourth terminal 31, of the switch 31 is also connected to the conductor 18 via a switch 33 closed when the load of laundry is of the order of 2 kg.

La borne 302 du moteur 30 est par ailleurs reliée directement aux premières bornes d'interrupteurs 34, 35, 36 qui sont fermés lorsque l'utilisateur a choisi les fonctions respectives suivantes : charge de linge de l'ordre de 4 kg, charge de linge de l'ordre de 3 kg, et égouttage (c'est-à-dire suppression de l'opération d'essorage).The terminal 302 of the motor 30 is also directly connected to the first switch terminals 34, 35, 36 which are closed when the user has chosen the following respective functions: laundry load of the order of 4 kg, laundry load of the order of 3 kg, and draining (that is to say elimination of the spinning operation).

La seconde borne de l'interrupteur 34 est reliée à une borne 374 d'un commutateur double 37, faisant partie du programmateur et analogue au commutateur 31, avec une autre borne 372 reliée directement au conducteur 18, une borne 37, reliée à la seconde borne de l'interrupteur 36 et une borne 37z connectée au contact commun 39, d'un second pressostat 39 sensible à un niveau N2 d'eau dans la cuve supérieur au premier niveau N, auquel est sensible le premier pressostat 19. Une borne 392 du pressostat est reliée à la borne commune 383 d'un commutateur 38 du programmateur dont la première borne de connexion 38, est reliée à la seconde borne de l'interrupteur 35 (charge 3 kg) et dont la seconde borne de connexion 382 est connectée à la borne 193 du pressostat 19.The second terminal of the switch 34 is connected to a terminal 37 4 of a double switch 37, forming part of the programmer and similar to the switch 31, with another terminal 37 2 connected directly to the conductor 18, a terminal 37, connected to the second terminal of switch 36 and a terminal 37 z connected to the common contact 39, of a second pressure switch 39 sensitive to a level N2 of water in the tank higher than the first level N, to which the first pressure switch 19 is sensitive. A terminal 392 of the pressure switch is connected to the terminal common 38 3 of a switch 38 of the programmer whose first connection terminal 38 is connected to the second terminal of switch 35 (load 3 kg) and whose second connection terminal 382 is connected to terminal 19 3 of the pressure switch 19.

Le fonctionnement d'un lave-linge étant bien connu on ne décrira ci-après que les étapes de ce fonctionnement qui sont nécessaires à la compréhension de l'invention.Since the operation of a washing machine is well known, only the steps of this operation which will be necessary for understanding the invention will be described below.

Après la mise en route les bomes 21, et 212 du commutateur 21 sont reliées entre elles. Dans le pressostat c'est la connexion 192-193 qui est établie, la cuve ne contenant pas encore d'eau. Dans ces conditions l'électrovanne 20 est alimentée, l'interrupteur 14 étant fermé (comme c'est le cas pendant tout le déroulement du programme).After starting the terminals 21, and 212 of the switch 21 are interconnected. In the pressure switch connection 19 2 -19 3 is established, the tank not yet containing water. Under these conditions the solenoid valve 20 is energized, the switch 14 being closed (as is the case throughout the course of the program).

Si la cuve doit être remplie au niveau N2 le programmateur et le câblage imposent que le commutateur 38 soit branché de façon que les contacts 382 et 383 soient reliés et que dans le commutateur 37 ce soient les bomes 372 et 373 qui sont reliées entre elles. Si, par exemple pour une faible charge, la cuve ne doit être remplie qu'au seul niveau N, le branchement est tel que le moteur 30 est alimenté pour que la connexion 382-383 soit rapidement ouverte lors de ce remplissage et qu'ainsi le niveau de l'eau dans la cuve n'ait pas le temps d'atteindre le niveau N2.If the tank must be filled to level N 2 the programmer and the wiring require that the switch 38 is connected so that the contacts 38 2 and 38 3 are connected and that in the switch 37 it is the terminals 372 and 37 3 which are interconnected. If, for example for a low load, the tank should only be filled at level N, the connection is such that the motor 30 is supplied so that the connection 38 2 -38 3 is quickly opened during this filling and qu 'so the water level in the tank does not have time to reach level N2.

Lorsque le hauteur d'eau dans la cuve a atteint le niveau désiré, par exemple le niveau N, en phase de lavage, sous la commande du programmateur l'interrupteur 13 est fermé et ainsi la résistance de chauffage 17 est sous tension car le thermostat 16 est lui aussi fermé, l'eau étant encore à la température inférieure à celle affichée et le pressostat 19 reliant la résistance 17 au secteur par la connexion des bomes 19, et 192.When the water level in the tank has reached the desired level, for example level N, in the washing phase, under the control of the programmer the switch 13 is closed and thus the heating resistor 17 is energized because the thermostat 16 is also closed, the water still being at the temperature lower than that displayed and the pressure switch 19 connecting the resistor 17 to the sector by the connection of the terminals 19, and 192.

Dans cette position le commutateur 31 est tel que les bornes 31, et 312 sont reliées entre elles; mais le moteur 30 n'est pas alimenté car ses bomes sont ainsi en court-circuit.In this position the switch 31 is such that the terminals 31, and 312 are interconnected; but the motor 30 is not supplied because its terminals are thus short-circuited.

Quand la température de l'eau atteint la valeur de consigne l'interrupteur 16 s'ouvre, ce qui interrompt l'alimentation de la résistance 17. A ce moment la connexion 31,, 312 reste encore établie. Dans ces conditions le moteur 30 est alimenté, ce qui permet d'atteindre rapidement, pres- qu'immédiatement, une position du programme pour laquelle s'ouvre la connexion 311-312 pour arrêter la rotation du moteur 30.When the water temperature reaches the set value the switch 16 opens, which interrupts the supply of the resistor 17. At this time the connection 31 ,, 31 2 remains still established. Under these conditions, the motor 30 is supplied with power, which makes it possible to quickly reach, almost immediately, a program position for which the connection 31 1 -31 2 opens to stop the rotation of the motor 30.

Ensuite le temps de brassage du linge, c'est-à-dire le temps qui s'écoule entre l'ouverture du thermostat 16 et la fin de la phase de lavage proprement dit, est fonction de l'état des interrupteurs 32, 33, 34 et 35. Dans l'exemple, comme on le verra ci-après, la durée de rinçage après ouverture du thermostat 16 est, pour une charge de 3, 4 ou 5 Kg de 33 mn, pour une charge de 2 kg, 21 mn et pour une charge de 1 kg, 15 mn.Then the time for stirring the laundry, that is to say the time which elapses between the opening of the thermostat 16 and the end of the actual washing phase, depends on the state of the switches 32, 33 , 34 and 35. In the example, as will be seen below, the rinsing time after opening the thermostat 16 is, for a load of 3, 4 or 5 kg of 33 min, for a load of 2 kg, 21 min and for a load of 1 kg, 15 min.

A l'issue de ce temps de brassage, le programmateur commande les interrupteurs pour alimenter l'électrovanne 23 afin de compléter le niveau de l'eau dans la cuve à la valeur N2 et la maintenir pendant 3 mn. A l'issue de cette période de refroidissement le moteur de la pompe 25 est alimenté.At the end of this brewing time, the programmer controls the switches to supply the solenoid valve 23 in order to fill the water level in the tank to the value N 2 and maintain it for 3 min. At the end of this cooling period the motor of the pump 25 is supplied.

Dans l'exemple donné ci-dessus, et qui sera illustré par le tableau ci-après, lors de la phase de lavage la connexion 311-312 est encore établie lorsque le thermostat 16 s'ouvre. Il peut cependant arriver que lorsque le thermostat 16 s'ouvre cette connexion soit déjà interrompue, la phase de chauffage de l'eau ayant durée un temps supérieur à une valeur donnée, par exemple 27 mn pour une charge de 5 kg. Dans ce cas le temps de brassage sans chauffage est inférieur à 33 mn.In the example given above, and which will be illustrated by the table below, during the washing phase the connection 31 1 -31 2 is still established when the thermostat 16 opens. However, it can happen that when the thermostat 16 opens, this connection is already interrupted, the water heating phase having lasted for a time greater than a given value, for example 27 min for a load of 5 kg. In this case the brewing time without heating is less than 33 min.

Pour une pleine charge du tambour, 5 kg de linge, les interrupteurs 32, 33, 34 et 35 sont tous ouverts.For a full load of the drum, 5 kg of laundry, the switches 32, 33, 34 and 35 are all open.

Pour une charge de 1 kg de linge, l'interrupteur 32 est fermé et le cablage est tel que certaines opérations sont supprimées ou écourtées. Dans ce cas par exemple on supprime un rinçage, c'est-à-dire lorsqu'arrive le début de ce rinçage les contacts 31, et 313 sont reliés entre eux pour alimenter le moteur 30 lors de cette phase et ainsi passer à la phase suivante de rinçage ou une autre phase du programme.For a load of 1 kg of laundry, the switch 32 is closed and the wiring is such that certain operations are eliminated or shortened. In this case, for example, a rinsing is eliminated, that is to say when the start of this rinsing arrives, the contacts 31, and 31 3 are connected together to supply the motor 30 during this phase and thus pass to the next rinsing phase or another phase of the program.

Pour une charge de 2 kg on établit pour supprimer un rinçage ou une autre opération, la connexion 311, 314. Pour réaliser cette connexion 31,-314, du fait de la configuration du commutateur, on établit une connexion 31,-313 et une connexion 313r 314.For a load of 2 kg, the connection 31 1 , 31 4 is established to suppress a rinse or another operation. To make this connection 31, -314, due to the configuration of the switch, a connection 31, -313 and a connection 31 3r 31 4 are established .

Pour une charge de 4 kg de linge l'interrupteur 34 est fermé et c'est la connexion 374-372 qui est établie pour alimenter le moteur 30 afin de supprimer ou raccourcir une ou plusieurs opérations. Dans l'exemple, pour cette charge, on ne diminue que la durée d'une phase de rinçage par rapport à un programme de charge 5 kg.For a load of 4 kg of linen the switch 34 is closed and it is the connection 37 4 -37 2 which is established to supply the motor 30 in order to suppress or shorten one or more operations. In the example, for this load, only the duration of a rinsing phase is reduced compared to a 5 kg load program.

Pour une charge de 3 kg, l'interrupteur 35 est fermé et pour alimenter le moteur 30 on établit, d'une part, une connexion 381-383 par le commutateur 38 et, d'autre part, une connexion 372-373. Dans ce cas, par rapport à une charge de 5 kg on supprime une opération de rinçage.For a load of 3 kg, the switch 35 is closed and to supply the motor 30 a connection 38 1 -38 3 is established on the one hand by the switch 38 and, on the other hand, a connection 37 2 - 37 3 . In this case, compared to a load of 5 kg, a rinsing operation is eliminated.

Le tableau ci-dessous donne un exemple de programme de commande de lave-linge :

Figure imgb0001
The table below gives an example of a washing machine control program:
Figure imgb0001

Dans la première colonne, à gauche, on a indiqué les charges de linge en Kilogrammes poids, dans la colonne "prélavage" le premier chiffre correspond à la durée de l'opération imposée par le programmateur et le niveau N2 ou N, correspond à la hauteur d'eau dans la cuve. Dans la troisième colonne indiquée "lavage" le niveau d'eau dans la cuve est toujours imposé à la plus faible valeur N,, pour permettre de compléter au niveau N2 lors de la phase ultérieure de refroidissement. Dans cette partie du tableau mentionnée "lavage" les premiers chiffres à gauche sont les durées approximatives en minutes de chauffage de l'eau dans la cuve pour un réglage du thermostat 16 à des températures de respectivement : proche de l'ambiante, 40° C, 60° C et 90° C. Ces durées ne sont pas imposées par le programmateur. Dans la colonne dite "lavage" la seconde partie concerne les durées de brassage sans chauffage pour les diverses températures indiquées ci-dessus. Ces durées sont imposées par un programmateur. Toutefois on a vu que si la durée de chauffage dépasse 27 mn la durée de brassage est écourtée pour que le temps total de l'opération de lavage ne dépasse pas une valeur prédéterminée. Ainsi pour les charges de 3, 4 et 5 kg la durée totale du lavage est imposée à 60 mn au maximum. Pour une charge de 2 kg la durée totale de la phase de lavage est d'au maximum 48 mn et de 42 mn pour une charge de 1 kg. Pour les charges de 3, 4 et 5 kg la durée maximum du brassage sans chauffage est de 33 mn; cette durée de brassage est de respectivement 21 mn et 15 mn pour les charges de 2 kg et 1 kg.In the first column, on the left, we indicate the laundry loads in Kilograms weight, in the "prewash" column the first figure corresponds to the duration of the operation imposed by the programmer and the level N 2 or N, corresponds to the height of the water in the tank. In the third column indicated "washing" the water level in the tank is always imposed at the lowest value N ,, to allow to complete at level N 2 during the subsequent cooling phase. In this part of the table mentioned "washing" the first figures on the left are the approximate times in minutes of heating the water in the tank for setting the thermostat 16 to temperatures of respectively: near ambient, 40 ° C , 60 ° C and 90 ° C. These times are not imposed by the programmer. In the column called "washing" the second part relates to the mixing times without heating for the various temperatures indicated above. These durations are imposed by a programmer. However, it has been seen that if the heating time exceeds 27 min the stirring time is shortened so that the total time of the washing operation does not exceed a predetermined value. Thus for loads of 3, 4 and 5 kg the total duration of washing is imposed at 60 minutes maximum. For a load of 2 kg the total duration of the washing phase is a maximum of 48 minutes and 42 minutes for a load of 1 kg. For loads of 3, 4 and 5 kg the maximum duration of brewing without heating is 33 min; this brewing time is 21 min and 15 min respectively for loads of 2 kg and 1 kg.

La quatrième colonne correspond à la phase de refroidissement qui est la même quelles que soient la charge et la température : niveau d'eau N2. durée 3 mn.The fourth column corresponds to the cooling phase which is the same whatever the load and the temperature: water level N2. duration 3 min.

Dans les colonnes R,, R2. R3 et F4 on a indiqué les durées des phases de rinçage en minutes et les niveaux d'eau N, ou N2.In the columns R ,, R 2 . R 3 and F4 the durations of the rinsing phases are indicated in minutes and the water levels N, or N2.

Enfin dans la dernière colonne on a indiqué les durées (en minutes) d'essorage.Finally, in the last column, the spin times (in minutes) are indicated.

Ce tableau a été établi pour du linge de coton. On notera toutefois que ce tableau correspond aussi au programme de traitement d'autres types de linge, par exemple pour une pleine charge de tissu synthétique l'utilisateur indiquera une charge d'au maximum 3 kg et la température de lavage est choisie en fonction de ce tissu.This table has been drawn up for cotton linen. Note, however, that this table also corresponds to the treatment program for other types of laundry, for example for a full load of synthetic fabric, the user will indicate a load of maximum 3 kg and the washing temperature is chosen according to this fabric.

Autrement dit les programmes de lavage sont pratiquement les mêmes quelle que soit la nature du linge, la seule différence étant la température de chauffage de l'eau. Cependant il est possible de différencier de façon plus importante les programmes de lavage en fonction du type de linge. A cet effet la came du programmateur qui agit sur les états des interrupteurs 21, 24, 31, etc... est divisée en plusieurs secteurs, par exemple trois, chaque secteur correspondant à un type de linge. La sélection du secteur est effectuée par l'utilisateur à partir du tableau de commande de la machine. Dans ce cas le rôle du moteur 30 est de raccourcir ou supprimer certaines étapes de fonctionnement lorsque la charge est inférieure à la charge maximale. Autrement dit dans ce dernier cas le moteur 30 a exclusivement un rôle d'adaptation du programme à la charge.In other words the washing programs are practically the same regardless of the nature of the laundry, the only difference being the heating temperature of the water. However, it is possible to more significantly differentiate the washing programs according to the type of laundry. For this purpose, the programmer cam which acts on the states of the switches 21, 24, 31, etc. is divided into several sectors, for example three, each sector corresponding to a type of laundry. The sector selection is made by the user from the machine control panel. In this case, the role of the motor 30 is to shorten or eliminate certain operating steps when the load is less than the maximum load. In other words, in the latter case, the motor 30 exclusively has the role of adapting the program to the load.

Le tableau montre par ailleurs que les conditions d'éxécution de la phase de refroidissement et du premier rinçage sont indépendantes de la charge de linge, alors que d'autres dépendent par leur durée et la quantité d'eau utilisée de la charge de linge. L'indépendance des conditions d'éxécution de la phase de refroidissement et du premier rinçage à l'égard de la charge de linge résulte de l'observation suivante : les lave-linge n'étant habituellement pas munis de dispositifs de dosage automatique du produit lessiviel, l'utilisateur choisit la quantité de tels produits introduits dans la machine. Le choix est habituellement tel que la quantité est excessive quand la charge de linge n'est pas maximale. Dans ces conditions si, lors du refroidissement et du premier rinçage, la quantité d'eau introduite dépendait de la charge, la dilution des produits lessiviels risquerait d'être insuffisante, ce qui altèrerait la qualité du rinçage et risquerait de perturber le fonctionnement de la pompe de vidange de l'eau en raison de la mousse. C'est pourquoi les durées et niveaux d'eau pour la phase de refroidissement et pour le premier rinçage sont indépendants de la charge de linge et correspondent à la charge maximum. En variante seules les conditions d'éxécution de la phase de refroidissement sont indépendantes de la charge, les conditions du premier rinçage pouvant alors varier avec cette charge.The table also shows that the conditions for carrying out the cooling phase and the first rinse are independent of the load of laundry, while others depend on their duration and the amount of water used on the load of laundry. The independence of the conditions for carrying out the cooling phase and the first rinse with regard to the load of laundry results from the following observation: washing machines are not usually fitted with automatic product dosing devices detergent, the user chooses the quantity of such products introduced into the machine. The choice is usually such that the quantity is excessive when the load of laundry is not maximum. Under these conditions if, during the cooling and the first rinsing, the quantity of water introduced depended on the load, the dilution of the detergents could risk being insufficient, which would alter the quality of the rinsing and would risk disturbing the operation of the water drain pump due to foam. This is why the durations and water levels for the cooling phase and for the first rinse are independent of the laundry load and correspond to the maximum load. As a variant, only the conditions for carrying out the cooling phase are independent of the load, the conditions for the first rinsing then being able to vary with this load.

On remarque aussi que, selon l'invention, la durée du prélavage est fonction de la charge.Note also that, according to the invention, the duration of the prewash is a function of the load.
